SFECIFICATION forming part of Letters Patent No. 621,228, dated March 14, 1899.

. Application filed February 12, 1898- Serial No. 670,099- N 111011613 To all whom, it may concern:

Be it known that I, JOHN L. CREVELING, of New York,in the county of New York, State of New York, have invented certain new and useful Improvements in Gas Tanks and Regulators, of which the following is a complete specification, reference being had to the accompanying drawings. i

The object of my invention is to produceimprovements in gas tanks and regulators of that class in which the regulator is incased or protected by the walls of the tank the pressure of the gas supplied from which it regulates, whereby the complete removal of the regulator from the tank or the substitution of one regulator for another is facilitated.

In the accompanying drawings, Figure I is an end elevation of an ordinary gas-tank supplied with one form of my improved regulator. Fig. II is a section of the same on the line II II of Fig. I. Fig. III is a view similar to Fig. II, showing the regulator removed. Fig. IV is a perspective view of the regulator shown in Fig. II detached from the tank. Fig. V is a central vertical section showing a modified form of tank-headand regulator inclosed therein. Fig. VI is an end elevation of the subject-matter of Fig. V complete. Fig. VII is a side elevation of the regulator shown in Figs. V and VI detached. Fig. VIII is a central'longitudinal section of a modified form of the gas-tank to which the regulator shown in Fig. VII, for example, isapplicable. Fig. IX is a view similar to Fig. VIII, showing a further modification of the gas-tank to which the regulator shown in Fig. VII is applicable.

Referring to the figures on the drawings, 1 indicates the outer wall or shell of an ordinary gas-tank, to which, as by means of a double row of bolts 2, is secured a head 3. The wall 1 is usually and preferably cylindrical in shape, and the head 2 possesses a gen erally convex contour. The latter is provided, as is best shown in Fig. III, with a recess or cavity 4, which is fitted to receive the bowl of the regulator. (Compare Figs. II and IV.) The bowl is preferably provided upon opposite ends with lugs 6 and 7, the latter being adapted to accommodate the valve-controlled influx-opening 8 and the former the effluxopening 9.

10 and 11 indicate lateral recesses in the head 3, opening into the recess 4 and adapted to accommodate thelugs 6 and 7, respectively. The influx-opening 8 in the lug 7 is adapted to communicate with the interior of the tank, as through a nipple 12, which when the bowl of the regulator is inserted into the recess 4 and the lugs thereof into-the recesses 10 and 11, respectively, is adapted to enter an aperture 14 in the wall 15, defining the recesses 4, 10, and 11. The nipple 12 is adapted by any usual or suitable mechanical contrivance-- for example, correlatively-tapering walls or the like-to make a gas-tight joint when the regulator is secured firmly in its place-that is to say, in the recesses in the head 2.

For securing the regulator in place bolts 16,

(see Fig. 1,) passing through bolt-holes 17 (see Fig. 1V) in the lugs 6 and 7, respectively, af-

ford simple and eifective means.

The regulator-bowl contains the usual pres- I sure-regulator mechanism, which, being Wellknown in the art, is not completely illustrated and does not here require detail description. Suflice it to say that it preferably embodies the well-known flexible diaphragm 18, which may besecured across the mouth of the bowl 5, as by aflanged annulus 19, fastened in place by a crown of bolts or screws 20. The outer face of the diaphragm 18 is preferably protected by a cap 21, screwed to the flange of the annulus 19.

The form of tank-head and regulator above described is shown in Figs. I to IV, inclusive.

In Figs. V to VII, inclusive, a modified form of regulator-bowl and tank-head to fit it'is illustrated.

In Figs. V and VI, 22 indicates the tankhead, that is provided with a regulator-recess 23, defined by a wall 24 of suitable shape.

25 indicates the bowl of the regulator, which fits snugly within the recess 23 and which is provided with an effluX-pipe 26 and upon its bottom with an externally-screW-threaded influx-pipe 27. The pipe 27 screws into a central internally-threaded aperture 28 in the wall 24. at the bottom of the recess 23 and affords suitable means for detachably securing the regulator within the recess 23 and also for supplying gas from the tank to the interior of the regulator.

In securing the regulator (shown in Figs. V to VII) within the recess 23 of the tankhead 22.01 in removing it from the recess it is only necessary to rotate the regulator-bowl in one direction or the other, as occasion may require. Then the regulator is in place in the recess 23, it may be secured against rotation, as by a set-screw or other suitable device.

Figs. VIII and IX show forms of small tanks-such, for instance, as are employed as receivers for the illuminating-gas in streetcarsin which the shells 1 are allowed to project over the heads 31 and 32, respectively, and thus form a receptacle and case for the regulator.

In Fig. VIII a concave head is shown fitted to and adapted to receive a regulator similar to that illustrated in Fig. VII and adapted, with a central internally-threaded aperture 33, for the reception of its threaded pipe 27.

In Fig. IX the interior circumference of the shell 1 is fitted to the bowl of the regulator and aifords sufficient support for it without a specially-fitted head. It is provided also with a central internally-threaded aperture 3i for the reception of the threaded pipe 27 of the regulator. (See Fig. VII.)

In small tanks, such as might be made of pipe, the bowl of the regulator might be threaded to correspond with threads in the end of the pipe or shell and the parts screwed directly together without the intervention of any other head, in which form the bowl of the regulator would constitute at the same time the head of the tank.

IVhat I claim is- 1. The combination'with a gas-tank provided at its end with a recess, of a regulator fitting within the recess, and means of communication between the interior of the tank tank head, of a regulator fitting within the re- I cess, means for establishing communication between the interior of the tank and the interior of the regulator through the head, and means foruniting the tank-head and regulator, substantially asset forth.

4. The combination with a recessed gastank head and regulator fitting within the same, of means of communication between the interior of the tank and the interior of the regulator through the head, and means for uniting the regulator and the tank-head, said means being adapted also to perfect the means of comm unication between the interior of the tank and the interior of the regulator, substantially as set forth.

5. The combination with a gas-tank head provided at its end with a recess, of a regulator fitting within the recess, an inlet-nipple upon the regulator, an aperture in the wall of the recess fitting said nipple, and means for forcing the nipple into the aperture in the wall of the recess, so as to perfect between them a gas-tight joint, substantially as set forth. I

In testimony of all which I have hereunto subscribed my name.
